Which Intel Chip for new Prommy Mach II?

[Amair_sc]

Hi guys!

I am going to be building a new system in the next few weeks and though it might jump to Intel (as you can see from my sig, an upgrade is long overdue). I am going to order a prommy mach II to cool this new baby and was wondering which was my best option with Intel (considering mobo, ram and cpu).

I considered the following:

CPU: P 2.4c (but might change, depending on motherboard and Ram)

Motherboard: I am really unsure on this, I hear the Max3 is theoratically the best but struggles with 5:4 and high vdimm in practice. Runner up is Asus with P4C800-E, as you can see, I need some help with this one!

Ram: Though about some nice PC4000, then read about the advantages of tighter timings with GAT. Contemplated Mushkin black lvl 2 pc3500 with bh-5 chips but then came back to the vdimm problems on the Max-3. also, I do not know how high I could push this 3500 even with vdimm=3.2v so I might have to get a higher multi than on the 2.4c

So there you have my dillema! I hope you guys can give me some ideas and perspective that will make the decision easier :) !

Thanks a lot for looking and thanks in advance!

I'd have to recommend the 2.6C (13 multi) Using the 5:4 divider you could get

Cpu: 3770
fsb: 290
memory: 232 (2-2-2-11 )

check the abit boards. everyone is having problems over 270. and if the voltage is fluctuating then its a board problem. YOu would have to RMA it and wait 6 weeks. A lot of people are having problems over 2.9V and 270.

If you are using a prommy mach II, get a P4 3.0C, or a P4 3.2C.

Most people with a 3.0C and a prommy get 4GHz easily. If you get a 3.2C you might get 4.2GHz.

Whatever you do, don't get a 2.4C. It's a good chip for air and water cooling, but it would never hit 4GHz.

3.0C (15multi) = requires 266fsb
266 is too high for ANY memory at 2-2-2 1:1
266 at 5:4 .....213 memory speed

vs

2.6C (13multi) = requires 307fsb
307-too high for 1:1
307 @ 5:4 ....memory@245

You should get

a 3.0 ghz

don't worry about aggresive RAM timings, just get some pc4000 at 3-4-4-8, you shoudl be able to get some good mem scores running at 1:1

If I remember correctly, more CPU and RAM Mhz was faster than lower Mhz with tighter RAM timings.

My memory isn't always that good though! :D

thats what i thought also, although i was not sure.... if i was getting a Mach II i would prolly get a 2.8 or 3.0 and some fast ram with not so tight timings rather than slow cpu and slow ram with tight timings

[zabomb4163]

Who said anything about slow cpu? the goal is usually to arrive at the highest fsb possible

[stan03]

slower* :) if you disagree sorry, just what *I* would do

[zabomb4163]

if he is interested in spending that much i'd go with an amd64.....ask anyone who currently owns a 4gig+ p4. almost all of them are currently favoring the amd64.

[stan03]

but he did say p4..... yea if i had that much money i too would get the FX-51.
